Calculate the atomic mass of an element containing a mixture of isotopes?
The only way is to look it up. The isotopic ratio can be determined on a mass spectrometer. Most periodic tables will have the atomic mass otherwise Google the element the wikipedia article will have the average mass of the element listed there. A few elements like Lead do have differing isotopic ratios depending where it was mined.
What is the percent composition of oxygen in lithium hydroxide?
The molar mass of LiOH is 24,01874. The atomic weight of oxygen is 15,9994.24,01874 g----------------100 %15,9994 g---------------------xx = 15,9994 . 1oo/24,01874 = 66 %
